System for automatic refilling water pitcher
View Patent ↗An automatically refilling water pitcher according to various aspects of the present technology is configured to provide a readily available source of drinking water that doesn't require an under sink storage tank or a countertop water faucet. In one embodiment, the system comprises a removable water pitcher and a water dispenser. The water dispenser is configured to be responsive to the placement of the water pitcher on a dispenser base and direct filtered water into the water pitcher in response to a signal indicating that the water pitcher is below a predetermined amount.
1 . A refillable water pitcher, comprising:
a removable water pitcher; and
a filling station, comprising:
a base disposed along a lower portion of the filling station for receiving the water pitcher;
a faucet disposed at an upper portion of the filling station and configured to direct an incoming water supply into the water pitcher;
a valve positioned inside of the filing station upstream of the faucet;
a sensor positioned in the base and configured to:
determine when the volume of water in the water pitcher is below a predetermined threshold; and
generate a signal if the weight of the water pitcher is below the predetermined threshold; and
a controller responsive to the signal from the sensor, wherein the controller is configured to open the valve to allow water flow to the faucet until the volume of water in the water pitcher is at the predetermined threshold.
2 . A refillable water pitcher according to claim 1 , wherein the sensor comprises a scale configured to weigh the water pitcher.
3 . A refillable water pitcher according to claim 1 , wherein the sensor is configured to determine if the water pitcher is removed from the base.
4 . A refillable water pitcher according to claim 3 , wherein the sensor does not generate the signal when the water pitcher is removed from the base.
5 . A refillable water pitcher according to claim 1 , further comprising an inlet positioned inside of the filing station upstream from the valve and configured to connect to an incoming water supply.
6 . A refillable water pitcher according to claim 5 , wherein the filling station further comprises a water line extending between the inlet and the faucet.
7 . A countertop water refilling station for a water pitcher, comprising:
a base for receiving the water pitcher;
a water inlet disposed within the base;
a water line disposed within the base and coupled at a first end to the water inlet;
a faucet coupled to a second end of the water line at an upper portion of the countertop water refilling station disposed above the base, wherein the faucet is configured to direct an incoming water supply from the water line into the water pitcher;
a valve positioned within the base and coupled to the water line upstream of the faucet;
a sensor positioned in the base and configured to:
determine when the volume of water in the water pitcher is below a predetermined threshold;
generate a signal if the weight of the water pitcher is below the predetermined threshold; and
a controller responsive to the signal from the sensor, wherein the controller is configured to open the valve to allow water flow to the faucet until the volume of water in the water pitcher is at the predetermined threshold.
8 . A water refilling station for a water pitcher according to claim 7 , wherein the sensor comprises a scale configured to weigh the water pitcher.
9 . A water refilling station for a water pitcher according to claim 8 , wherein the scale is configured to account for an empty weight of the water pitcher when determining if the volume of water in the water pitcher is below the predetermined threshold.
10 . A water refilling station for a water pitcher according to claim 7 , wherein the sensor is configured to determine if the water pitcher is removed from the base.
11 . A water refilling station for a water pitcher according to claim 10 , wherein the sensor does not generate the signal when the water pitcher is removed from the base.
